When laying new floor we had to use concrete auto-leveler over an expansion join as one joint was slightly higher than the other.

Work I did myself: Installed new ceramic tile in the kitchen, basement, and bathrooms; painted; installed new kitchen appliances; installed new garage door; installed new screen door; updated landscaping; replaced water heater; updated bathrooms; added kitchen cabinets.

As a new real estate investor I think it's crucial to lay down a foundation of systems that will propel you to the next deal. 

If you plan to hold, having new plumbing, electrical, tile, cabinets, etc will be nice as well. 

We've been in the house 6 years, and we've done a good amount of remodeling- drain tile in backyard, fenced in backyard, new high efficiency furnace, remodeled bathroom and kitchen.

I don't have tens of thousands just laying around.

We pushed the wall into Master bedroom further, and made a huge full tile shower, and double vanity.

Look up the costs of materials for various things (Flooring, cabinets, granite, shower tile, vanities, fixtures, fans, windows, doors, baseboards, etc) and then look up the local flooring installers, cabinet installers, countertop fabricators, shower tilers, window installers, etc. and ask them how much they charge for labor on certain things.
